EVANS, or '.iULsA, OKLAHOMA; YsAIU EVANS AssIGNoR" 3 Y 'ro sAIn- Donn GAS BURNER 7 This invention relates tonew and useful improvements in burners, and particularly to burners for use in connectionlwithV natural Gas. f f t? One Object of the invention is to provideA a burner which is especially adapted for use in connection with large boilers and furnaces, and which will produce' the maximum amount of heat with the expenditure of the minimum amount of fuel.

Another object is to provide a burner o this character which is adapted to be used in series'or gangs, and wherein each burner will receive the same amount of as and air, and wherein such air will be fe to the burners in proportion to the pressure of theAV gas.

A further object is to provide a burner wherein, when used in series or gangs, each individual burner unit maybe readily and easily removed and replaced, without dis-` turbing the remaining units.

Other objects and advantages will be apparent from the following description whenV taken in connection with the accompanying drawings. v l

In the drawings:

Figure 1 is an elevation of a gang o-r series of burners madein accordance with the present invention. i

Figure 2 is a top plan view of one of the burners. l

Figure 3 is a vertical transverse sectional view on the line 3-,3 of Figure2.

Figure 4 is a. sectional view on the line 4 4 of Figure 2. Y

Referring particularly to the accompanying drawings, 10 represents a tube or pipe which conveys the gastov the burners,.one end Vbeing connectedv with a sourcewof gas supply, `while the other fend is closed. Velded, or otherwise properly secured, on. the upper face of `this pipe 10, and extend'- ing transversely thereof, are the pairs ofjbars 11, each having its ends turned upwardly` and inwardly, Vas shown at 12. In theupper side ofthe pipe 10,- intermediate the pairs of bars 11 is a gas openingl. 4 An elongated, semicylindrical guard plate 14is disposed over each of the openings 13, and has its marginal edges engaged with the upturnedends l2', of the bars 11, whereby said plate is propi. n

erly `held in position. In the intermediate portion of the crest of the plate 14 there .is-

secured an upwardly extending nipple 15,

the upper end of which is engaged int the ,lower end of the vertical pipe'16. On the upper end of the pipe V16 is mounted the. Vburner head,represented asv a whole by the numeral 17, said head comprising an approxf imately` cylindrical body 18 the upper face 'i ofV which is depressed longitudinally, as

shown at 19, and formed in: the wall 19, ad-

jacent each long edge, are thelongitudinal i seriesof gas outlet openings 20, such open-y ings being so arranged that theflames from one set of openings will be directed at an angle toward the other set of flames.` It will l be particularly 'noted that the openings 13 arev arranged directlybeneath, but in spaced relation below the lower end ofthe nipple 15, so that as the gas passes from said Vopening to said nipple, it passes across an air space and mixes with, and draws air' up into l the nipple, andthence through the pipe 16 to the burner head.

Y It will be further noted that the gas outlet openings 20 are of smaller diameter than the entrance opening from the pipe 16 to the burner head, whereby gas will collect in said f head and issue fromtheopenings 20 with great force, thusgre'atly increasing the fin-f tensity ofthe flame.A l

When a burner is to be replaced by a new 'Y one, due to the fact that the old one has be- Y come worn out, such old burnermay be easily and quickly'removed, without'disturbing thev Y remaining burnersfby simply detaching the" l. pipe lvfrom the nipple 15, and engaging the' pipe of the newburner with` said nipple. y

While we have 'shown individual` plates 14, for they burners, we wish it understood that there may be provdedalong plate' having a plurality of the nipples 15, regularly spaced, v

for receiving Vthe tubes 16. Also, while VVwe have shown the heads 17 as arrangedin lon-V gitudinal alinement, such heads 'may be disl posed transversely of the pipe 10, so as to v lie in parallel relation to each other.`

What is claimed is: A gas burner comprising a supply Pire im having a gas outlet in its upper side, transverse supports on the pipe, an elongated arcuv ate guard mounted on the supports having a nipple extending from its upper side direct- 1y over said outlet, a burner head of approximately oylindrical form having its upper side depressed "longitudinally and having 1on-g`-- tudinal series of gas orifices adj acent vits sideS, and a pipe carried by the burner headv and?)YV detachably engaged 011 the nipple.

In testimony whereof We ailix our signa-- tures. l
